A harddisk has the following specifications: i) average seek time of 3ms, ii) 12000 RPM and ii) data transfer rate of 160 MB/sec. Calculate the random throughput (R) and the sequential throughput (S) for the harddisk assuming 4KB block size for random reads and 100 MB sequential reads. Explain the low random write speeds for RAID-4. How is this addressed in RAID-5?
